Antiviral dynamics and sex differences of zidovudine and lamivudine triphosphate concentrations in HIV-infected individuals

Abstract

Zidovudine and lamivudine triphosphate concentration thresholds were independently associated with the antiviral activity of zidovudine, lamivudine, and indinavir. The significantly elevated triphosphate concentrations in women and individuals with low baseline CD4 cell counts, groups that historically experience high rates of serious NRTI toxicities, provide a hypothesis for the pathogenesis of these events.
